Abstract
Multi disk turbine MDT is a bladeless device that allows to convert energy from low energy availability streams. In this study, the static torque of an laboratory MDT prototype is measured for different rotor configurations under 5 inlet air pressure levels. Rotor is assembled with 5 different disk number, from 0 to 4 parallel disks (Type A assembling) followed by a study of spacing combination with 2 disks (Type B assembling). 35 tests in choked flow condition are presented and the influence of the number of disks represents a 50% enhancement of the initial static torque value. Disks spacing also displays a static torque increment of 17%. Taking into account only the effect of increasing the inlet pressure, results show a rise in torque up to 2.45 times its initial value. Finally, considering all the effects together, torque increased from 0.28Nm to 1.2Nm, which is a rise of around 4 times its initial value.
